Physics 1st Semester Review 1 of 2

Front

What is mass?

Back

The amount of matter in an object.

Front

What is the missing force when an object is in motion?

Back

Frictional force.

Front

Calculate the acceleration of a car that goes from 50 mph to 80 mph in 5 seconds.

Back

6 mph/s.

Front

What does Newton's 3rd law state?

Back

If an object exerts a force on another object, the second object exerts a force of equal strength in the opposite direction.

Front

Which law explains why a soccer ball moves faster than a bowling ball when the same force is applied?

Back

Newton's 2nd law.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

Define weight.

Back

The force of gravity acting on an object's mass.

Front

What is the formula for acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is Newton's 1st law?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is the relationship between mass and weight?

Back

Weight is the gravitational force on an object, calculated as Weight = Mass x Gravity.
